T0 072 w71 om it may concern Be it known that I, Jnnvrs It. Hansson, a citizen of the United States of America, residing at Detroit. in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Packaged-leading Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to machines for securing the heads to the bodies of packages, and particularly for securing a metallic flanged head to a paper or fiber body.

It is the object of the invention to obtain a construction particularly adapted for use wi th packages of non-circular form. and the invention consists in the construction as hereinafter set forth.

In the drawingswligure l is a plan view of the machine; and Fig. 2 is an elevation thereof partly in section.

In attaching metallic caps to fiber packages. it is usual to provide a flange on the head fitting inside the body and provided with a portion extending over the edge of the body and outer surface thereof. rl`his outer portion is pressed inward by the heading` machine. so as to clamp the body and hold the head in enga gement.

In applying heads to circular bodies, the seaming operation mav be performed bv the presure of a roll or diskmovable radially with respect to the axis of the head, but Where the head is of non-circular shape it has been found that the Work will not be satisfactorily performed by such a construction. rl`hus Where square or oval cans or packages are operated upon, the seaming roll will not instantaneously follow the retreatingr part of the surface, which produces a pounding action, with unsatisfactory results.

Mv present invention .involves the discovery that bv arranging the movement of the scaming roll in relation to the rotating head support in a path oblique to the common plane of the axis of the seaming roll and rotating head support, perfectly satisfactory results may be obtained in the performance of the Work upon oval, square, or other noncircular shapes. The amount of deflection necessary is comparatively sli ght but it pro duces a marked difference in the action and the character of the result. It is however, necessary that the deflection should be toward the advancing side of the Work.

As shown in detail, A. is a rotary head support represented as of rectangular form, B is a seaming pressure roll which is journaled'in the shank C. slidably engaging the gui des D and yieldably pressed by the spring E.

F is a movable member carrying the roll B and shank C and upon which the guides D are mounted. To the movable member F a lever F is fixedly secured and forms with the same a bell crank adapted to turn about the stationary pivot F2. The outer end of the lever li" is slotted as at F3 for enga ging the pin Gr upon the handle Gr pivoted upon a stationary pivot H. rl`hus, the action of the handle G will rock the member F upon its pivot F2 and move the roll B toward or from the rotary head support. The relative arrangement of the parts is such that when the member F is moved to a position in which the roll B performs its Work, the guides D will be arranged so that the forward movement of the shank C is in a path at an angle to the common plane of the axis of the seaming roll and rotating head, the deflection being toward the advancing side of the rotating; head. I have found that with Work of a diameter not to exceed three inches or thereabout, a deflection of the center of the roll one quarter of an inch from the common axial plane of the head support and roll, will produce satisfactory results, but the proper degree of dedection for modified constructions can be best determined by experimentation.

In operation, the heads with the bodies in engagement therewith are placed upon the head support A and revolved thereon` While the member F is moved by the handle G to press the roll B in Contact With the flange of the head which is to be seamed. During this operation, the roll Will be vibrated against the tension of the spring E by the change in radius of the succeeding portions of the head, and it Will be noticed that upon the retreating portions of the head the roll travels backward or opposite to the direction of rotation of the head, which, as has beenl circular heads, of a seaming roll, a spring lfor' yieldably pressing said seaming roll to- Ward said support, a shank to which said seaming roll is journaled, and a guide for said shank for directing said roll in a plane deiected from the common axial plane of said head support and roll toward the advancing side of the work.

In testimony whereof I affix my signature 1 (logies` of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents,
